(1) where Cmis the mass/volume concentration in mg m−3, Cvis the concentration (v/v) in ppm, M is the gram molecular weight (CO2 = 12 mg/mol, CH4 = 12 mg/mol, N2O = 28 mg/mol), P is the atmospheric pressure, R is the universal gas constant and T is...
where\(\beta\)is the coefficient of the independent variable, and\(W\)is spatial weight matrix.\(\theta\)refers to the spatial lag coefficient of the independent variable, indicating the effect degree by the independent variable in surrounding regions on the dependent variable in the local regio...
In particular, high molecular weight PPC from rare earth ternary catalyst is becoming an economically viable biodegradable plastic with tens of thousands of tons produced per year, providing a new solution to overcoming the problem of high cost in biodegradable plastics (Qin and Wang, 2010...

We investigated their conformation and aggregation as a function of composition and molecular weight of the copolymer, concentration, pressure and temperature. Generally, the gradient copolymers form small aggregates with low mean aggregation numbers between 1 and 10 and radii of gyration in the range...
Afterward, a calculated amount of PVP (to keep the concentration ratio MPVP/MM2+ = 5, M of PVP was calculated based on the molecular weight of its monomer) was added to the above solution and further stirred for 30 min. The mixture was transferred into a 100 mL of Teflon-...
